Collégien is a family run business, based in Paris, and manufacturing in the Southwest of France since the 1930s. We bought a pair of their slipper socks for Clemence just after her first birthday and were totally sold.
The soles are super flexible, grippy, incredibly comfy and breathable. The uppers are beautifully soft and expertly detailed. AND they are machine washable. So versatile. We love them!
